[ADD] website: added support for invoking a server action through controller

website: added website/action/<id_or_xml_id> route, that runs the server action designed
by its id or xml_id. Only code server action returning a template give a result. The
template is displayed. Other or not existing server actions redirect to the homepage.

website: added an override of ir_actions_server: evaluation context gets request for
evaluation, to enable request.render(template_name); also returns template the same
way action is returned for code server action;
